From 5343e674f32fb82b7a80a24b5a84eee62d3fe624 Mon Sep 17 00:00:00 2001
From: Christian Lamparter <chunkeey@googlemail.com>
Date: Mon, 18 Apr 2016 12:57:41 +0200
Subject: [PATCH] crypto4xx: integrate ppc4xx-rng into crypto4xx
This patch integrates the ppc4xx-rng driver into the existing
crypto4xx. This is because the true random number generator
is controlled and part of the security core.
